There are gameplay bugs with Evasion, Armor, and Resistance. For reference, I am playing on Xbox One S.
Evasion: it seems like all percentages are applied as percentage multiplication of V's original value of 1, which means that when you get an Evasion increase of 4%, rather than 5% total evasion, you get 1.04. The end result is that Evasion never goes above 2 or 3. It seems from gameplay that V is meant to go up to values of 70 or 90.
With Armor, the armor buff from the technical tree is not applying correctly. I have checked values before and after increasing the technical attribute, without any increase in the armor stat itself.
Resistance: Some items and abilities add to resistance correctly. Some, such as the legendary cyberware Cataresist, do not. Before applying Cataresist I had 12 resistance, after I had 16. This means that Cataresist was also applying it's stats as a multiplier to the base Cataresist stat, not adding via addition. As a means of comparison, the perk that boosts resistance in the Cold Blood tree adds more resistance via addition, which feels like the correct way of doing things.
The end result of all these bugs is that V feels much, MUCH more fragile than they should be. V tends to die almost instantly on hard mode to NPC's of the same level range.
